1. What is the Compost Calculation?

The compost calculation determines the volume of compost needed for a given area at a specified depth. It helps gardeners and landscapers estimate the amount of compost required for their projects.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( \text{Area} \) — The surface area to be covered (in square meters)
• \( \text{Depth} \) — The desired depth of compost layer (in meters)
• 1000 — Conversion factor from cubic meters to litres

Explanation: The equation calculates the volume in cubic meters and converts it to litres (1 m³ = 1000 L).

3. Importance of Compost Calculation

Details: Accurate compost calculation ensures you purchase the right amount of material, avoiding waste or shortages. It helps with budgeting and planning garden projects.

4. Using the Calculator

Tips: Enter the area in square meters and desired depth in meters. Both values must be positive numbers. The result shows the compost volume in litres.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure my garden area?
A: For rectangular areas, multiply length by width. For irregular shapes, divide into smaller rectangles or use an online area calculator.

Q2: What's a typical compost depth?
A: For general soil improvement, 5-10 cm (0.05-0.1 m) is common. For new beds, 15-30 cm (0.15-0.3 m) may be needed.

Q3: Can I use feet instead of meters?
A: First convert to meters (1 ft = 0.3048 m) or use a calculator with imperial units.

Q4: Does this account for compaction?
A: No, this calculates uncompressed volume. You may need slightly more to account for settling.

Q5: How many bags will I need?
A: Divide the total litres by the bag size (e.g., 1000 L ÷ 40 L/bag = 25 bags).
